In some cases, asset minification can cause CSS or JavaScript code to break, often resulting in visible errors on the frontend. If you notice unusual issues on your site after asset minification, we recommend working with a developer to identify the problematic assets. After that, you can use the “Minify” feature in manual mode, which allows you to prevent minification of specific CSS and JavaScript files.

Opcode Cache
WordPress is a dynamic CMS, meaning PHP threads are constantly executing code in the background. Opcode cache helps speed up your site by storing compiled PHP code, making subsequent requests that require the same code faster.

If your site is hosted at Kinsta, you don’t need to worry about enabling an opcode cache layer in W3 Total Cache. We enable OPcache, an opcode cache, on all live environments. OPcache is disabled on live cyprus phone number data environments to ensure that compiled PHP code is not cached and does not interfere with site development and debugging .

If your host does not offer opcode caching, we recommend enabling it in W3 Total Cache. Please note that the opcode caching feature is only available in the Pro version of W3TC.
